Abstract
ALIGNMENT AID FOR GOLF CLUBS
Abstract of the Disclosure A golf club is provided with an alignment device for indicating when the face of the club is properly aligned. The alignment device comprises a linearoptic screen or lenticular decal which provides a three-dimensional indicator, such as a line which appears below the top surface of the screen, for indicating when the face is aligned.

Description
2~9~684 Baçk~roun~
This invention relates to gol~ clubs, and, more particularly, to an alignment aid ~or indicating wh~n a gol~
club is properly aligned.
A golf club, for example, an iron typs oP gol~ club, includes a hitting face for strikilg a gol~ ball~ I~ the gol~
club iS to hit the gol~ ball accurat~ly, the hitting face must be properly aligned with tha intended linQ o~ ~light o~ the ball. For a straight ~hot, i.e., a shot ~or which th~ player doa~ not intend to impart dra~ or ~Eade ~pin to the ball, the club face mu~t be aligned squar2 to the targ~t line. The club face o~ an iron i5 square to the target line wh~n the plane o~
the ~acQ i~ perpendicular to a vertical plan~ along the target line. Tha faca o~ a wood type o~ gol~ club conventionally includes bulge and roll curvature, and a wood club is square to the target lin~ wh~n a plana which i~ tangent to th~ center of the face is perpendicular to a vertical plane along the target line.
Many gol~er~, particularly b~ginnlng golfer~, have difficulty in d~t~ining wh~n a gol~ cl~b i8 prop~rly aligned.
Even accompli~h~d golfers periodically experi~ncQ proble~ with align~ant. BQcau~ a play~r i9 standing to ona 5ide of the targat lin~ and c~nnot look down the targ2t lin~ when he addresses the golf ball, it is di~icult to deter~in~ when th~
club f~ce i~ square. I~ th~ player intends to '~workN the ball by closing or openiny thQ ~ac~ o~ the club at addre~ is difficult to d~t~rmine the degree to which the club ~ac~ is closed or open relativ~ to th2 tar~et lin~. The pro~lem of alignment is suc~l that many golf~r~ cannot be ~ur~ that the club faco i~ properly aligned without th~ as~i~tanc~ o~ another p~r~on who ~tands~ b~hind th~ playQr ~long ~h~ target line and ob~erve~ th~ po8ition of th~ elub fa~.

~0946B4 S~3~y Q~ ~he I~Y~atl~n The inventlon provides a ~imple alignment d~vice which is mounted on tha golf club and which enables the gol~er to determine when the club face i~ properly aligned without the assistance of another person. The alignment device comprises a linearoptic or lenticular ~creen which provides a three-dimensional visual image o~ an indicating mark below the sur~ace o~ the screen. When the position o~ the screen changes relative to th~ gol~er's eyes, the position o~ the ind$cating mark changes at a magnifiQd rate, thereby providing a readily apparent indication o~ the po~ition of the club Pacs~ In one embodiment o~ the align~ent devicu the screen provides the image of a line which i~ aligned with lines on th~ cl~b above and below tha screen when the club face i5 aligned sgu~re to the target. When the club shart and club ~ace are rotated li~htly out of alignment, the line on tha screan moves out of alignment with the lines on the club. In anoth~r embodiment o~ th~
alignm~nt devica no imag~ i~ vi3ible on the ~creen when the club face is properly aligned, but an indicating ~ark or color become~ vi~ibl~ i~ thQ club is rotatQd out of align~ent in either directlon.
